The most common cause for mobile device registration failure is a miss-configuration in Active Directory.
To register the device, the users email address must reside in the
Email field of the user's profile.
Attempt the following:
- In Active Directory Users and Computers, look for the user user.name.
- Right-click the username and click Properties.
- On the General tab, look for the E-mail text box.
- Verify that E-mail: is set to [email protected].
- Test.
If the above does not solve the problem, try a different email domain.
For example:
Instead of configuring
example.com.tw as their email domain, use
example.com (make sure they also update the user-profile in AD again).
This should resolve the issue.
